IMPROVEMENT IN QUARTZ-CRUSHERS.

Specification forming part of Letters Patent No. 53,552, dated April 7,1866.

To all whom it may concern:

Be it known that I, S. F. AMBLER, of Tuolumne county, California, haveinvented, made, and applied to use certain new and useful improvementsin the Construction and Operation of Mortar Boxes or Beds for FloatQuartz-Batteries; and I do declare the following to be a full, clear,and correct description of the same, reference being hadto theaccompanying drawings, making part of this specification, and to theletters of reference marked thereon, in which Figure l is a frontsectional view of a twostamp float quartz-battery Fig. 2, an end view ofthe same.

In the drawings like parts of the invention are designated by the sameletters of reference.

The nature of my invention consists in attaching to the mortar box orbed A of a float quartz-battery a strip or flange, c, which strip orflange 0 extends along the inside of the discharging-edge of the box orbed A, thus effectually preventing the stamps in their operation fromforcing out of the box or bed A the course material, and causing, as itwere, a natural overflow of the pulverized material.

The screen ordinaril employed in conjunction with the mortarbox or beddoes not fully separate the pulverized quartz, and a screen sufficientlyfine for this purpose cannot be used, as the same is apt to be choked upor broken.

By the employment of the strip or flange 0. as shown, an advantage ofgreat moment is secured in that a means for facilitating the dischargeof the finer particles is afforded as the same rise from the bottom ofthe box A and pass off with the water over this strip or flange. Thusthe use of a screen is entirely dispensed with, while agreat saving oflabor and time is accomplished.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The strip or flange 0, attached to the mortarbox A of a floatquartz-battery, substantially as shown, for the purposes set forth.

S. F. AMBLER.
